Quantum Optics and Photonics

The Quantum Optics section conducts experimental and theoretical research in Quantum Optics, in particular, in Quantum Information Processing, Quantum Sensors , and Quantum Technologies. 

We use photons, from optics to microwaves interacting with a wide variety of quantum matter, such as quantum dots, single atoms, atomic ensembles and mechanical oscillators.

The overarching theme is generation and manipulation of non-classical entangled states for quantum simulation, sensing and communication. The research directions span from fundamental research to device engineering.

The section consists of four experimental groups and a theory group.


































































































Center for Hybrid Quantum Networks (Hy-Q)

The vision of the Center for Hybrid Quantum Networks (Hy-Q) funded by the Danish National Research Foundation is to exploit and implement novel approaches to interfacing different solid-state quantum photonic systems.

Hy-Q logo

A hybrid route to quantum networks is pursued in a “best of all worlds” approach where the advantages of the different platforms are utilized. Key research areas include deterministic emitter-photon and spin-photon interfaces for single-photon and multi-photon sources, long-lived mechanical membranes for quantum memories, and solid-state spin physics.

The long-term perspective of the research is to enable large scale processing of quantum information over global distances, also known as The Quantum Internet.


QUANTOP – Center for Macroscopic Quantum Systems

The Center runs quantum experiments with macroscopic systems, such as ensembles of hot and ultracold atomic spins and mechanical oscillators.

QUANTOP – Center for Macroscopic Quantum Systems

Macroscopic quantum systems provide unique opportunities for measurements beyond standard quantum limits which we apply for sensing magnetic and gravitational fields. We engineer novel quantum states of atomic and mechanical systems using interaction with photons. Original concepts such as measurements in the negative mass reference frame, quantum teleportation and quantum entanglement of macroscopic objects are developed and studied experimentally in our laboratories.

The Center is supported by the Villum Investigator grant, the European Research Council Advanced grant and is involved in the European Quantum Flagship project.
